v0.4.0 final review: D404 pad-centred aim (N64-parity quadratic curve) + full campaign-playtest sign-off bookkeeping

- input.c: padDirectCompute() — pad twin of the mouse Centred aim; the natural
  pitch path routes AIMMODE_CENTRED through it, AIMMODE_N64 keeps classic
  stick-deflection behavior. Parity pass uses bondview2's verbatim N64
  quadratic curve (sign(v)*clamp(defl/70,+-1)^2 * fov/60 * 3.5 deg/poll), so
  full-stick Centred matches N64's top rate exactly.
- optionsoverlay: aim rows device-neutral (Aim style / Aim range).
- findings.md: D404 RESOLVED (user-validated on Steam Deck, both passes);

 **Known issues:**
 
-- Some muzzle flashes draw an extra, erroneous long flash straight up from

-  drawn flash. Cosmetic only (D303).
-- Water levels show a moving seam between two water patterns (D245).
-- Occasional z-fighting on some levels' geometry (D308) — a Dam intro/
-  truck-wheel instance showing odd transparent-looking areas may be related
-  (D306). Minor and cosmetic.
-- In-level security camera props (not the player's own view) can
-  occasionally end up facing backwards on some levels, seen on Bunker
-  (D307). The orientation math has been verified faithful to the N64; if you
-  see it, a report of which level and which camera is what's needed to keep
-  chasing it.
-- Rarely, Bond's model can briefly render out of place after an animation
-  transition — purely visual: no effect on gameplay or saves, and it clears
-  on its own or by re-entering the level (D311).
 - On Facility, if gas leaks during Ourumov's monologue he can pause for up to

-- Distant geometry can drop out on the biggest open levels (Streets,

 - **`All unlocked` is experimental: back up `data/ge007.eep` before enabling
